Bifference between high frequency inverter and low-frequency

With the rapid development of the solar energy industry, inverters have been widely used in various photovoltaic solar energy systems. According to the different working frequencies, the inverter can be divided into high-frequency inverter and low-frequency inverter. This paper will explore the differences between the two in detail.

 

Difference between high-frequency inverter and low-frequency inverter–Working principle

Low-frequency inverter: the usually uses the power frequency transformer, by changing the transformer turn ratio to obtain the required output voltage. Low-frequency inverter has a simple circuit structure, and stable and reliable operation, but the large volume and relatively low efficiency.

High-frequency inverter: The high-frequency inverter adopts the high-frequency transformer, which realizes the voltage conversion through the high-frequency pulse width modulation technology (PWM). Due to the high working frequency, the high-frequency inverter has a small volume and a high efficiency.

 

Difference between high-frequency inverter and low-frequency inverter–Performance characteristics

Low-frequency inverter: the advantage lies in its simple and reliable circuit structure, suitable for the efficiency and volume requirements that are not high occasions. In addition, because the low-frequency inverter uses the power frequency transformer, the cost of the magnetic core material is low.

High-frequency inverter: the advantage of a high-frequency inverter lies in its high efficiency and miniaturization characteristics. Due to the use of high-frequency PWM technology, the conversion efficiency of the high-frequency inverter can reach more than 90%. In addition, the high-frequency inverter is small, which can save space and is easy to carry.

 

Difference between high-frequency inverter and low-frequency inverter– application scenarios

Low-frequency inverter: this is mainly used in occasions where the efficiency and volume requirements are not high, such as at home, office, and other fixed places of power supply. In addition, the low-frequency inverter is also suitable for some occasions that need long-term stable operation and high-reliability requirements, such as industrial control systems, data centers, etc.

High-frequency inverter: High-frequency inverter is mainly used in occasions with high volume and efficiency requirements, such as mobile power supply, electric vehicles, solar power generation systems, etc. Because the size of the high-frequency inverter is small and easy to carry, it is very suitable for mobile power supply electric vehicles and other occasions that need to move frequently. In addition, the high efficiency of the high-frequency inverter also makes it widely used in the solar power generation system.
